Daily US Times, Florida: The Saudi gunman who killed three sailors at Pensacola naval base, Florida had lodged an official complaint against one of his instructors.
The instructor called him a disparaging nickname in front of ten other students.
Report says he was ‘infuriated’ by this ‘shame’.
Last Friday 21-year-old Mohammed Alshamrani killed three soldiers at the naval base before he was shot dead.
The FBI presumed this as a terrorist attack.
They are trying to find out whether Mr Alshamrani acted alone or he has a connection with some other groups.
Florida’s governor, Ron DeSantis called for more stringent security measures after the incident.

He also urged that the gunman had “a major social media trail”.
Governor claimed, the gunman had a lot of deep-seated hatred for the US.
“My view is that… for us to be bringing in these foreign nationals, you have to take precautions to protect the country”, he said.
Other Saudi students at the Pensacola base had been questioned but not arrested.
The Saudi nationals are reportedly confined to the base and helping with the investigators.
The New York Times reports quoting people involved in flight training. The instructor called Alshamrani as “Porn Stash”.
Alshamrani is said to have written in his complaint, ‘”I was infuriated as to why he would say that in front of the class”.
